Does a security company need a licence in Florida?
Last checked August 2026
Yes. Installing, servicing or monitoring alarm systems for money is a licensed contracting trade in Florida under state law, and it comes in two classes: one that covers every kind of alarm including fire, and one that covers everything except fire. You can check any company's licence yourself in a couple of minutes, free, on the state's own register.
What the law actually says
Florida law defines an alarm system contractor as a person whose business includes contracts requiring the skill to lay out, fabricate, install, maintain, alter, repair, monitor, inspect, replace or service alarm systems for compensation. That definition is deliberately broad, and the important word in it is "monitor" — the licence is not only about the person on the ladder.
The statute then splits the trade into two classes, and the difference between them is fire.
| Class | What the statute says it covers | In plain terms |
|---|---|---|
| Alarm system contractor I | "all types of alarm systems for all purposes" | Everything, fire alarm systems included. |
| Alarm system contractor II | "all types of alarm systems other than fire, for all purposes" | Burglar alarms, cameras, medical alert and the rest — but not fire. |
Florida Statutes § 489.505, definitions of "alarm system contractor", "alarm system contractor I" and "alarm system contractor II". Quoted from the statute text at leg.state.fl.us, read 2 August 2026.
How to check a company yourself
The state runs a free public register of everyone it licenses, and it takes about two minutes. Go to the Department of Business and Professional Regulation's licensee search at myfloridalicense.com and look the company up. You can search by name, by licence number, or by city and county if you only half-remember who you spoke to.
- Ask the company for its licence number before the quote, not after.
- Search that number on the state register and confirm it comes back as active.
- Check the name on the licence matches the company on your paperwork — trading names and licence holders are not always the same.
- Check the class covers the work you are buying, especially if fire is involved.
A company that gives you the number without hesitating has been asked before and is used to it. Hesitation at this question is worth more information than anything else in the conversation.
Why this matters more than it sounds
It is easy to treat a licence check as box-ticking. It is not. The licence is what connects the person drilling into your wall to a regulator you can complain to, and to the insurance that pays when something goes wrong in your house. Without it you have a receipt and a phone number.
It is also the single cheapest filter available to you. It costs nothing, it takes two minutes, and it happens before anyone has your address.
Licensing is not the same as being good
A licence is a floor, not a recommendation. It tells you the company met the state's requirements and can be held to account. It tells you nothing about whether the install will be tidy, whether anyone answers the phone in December, or whether the monthly price doubles in year two.
So check the licence first because it is fast and disqualifying, then spend your actual attention on the contract and the monitoring arrangement, which is where the money and the disappointment live.
The door-knock problem
Summer in Florida brings door-to-door alarm sales, and it is the situation where the licence check matters most and gets done least. The pitch is usually some version of a free upgrade, a neighbourhood promotion, or a claim that your current company has been bought out and they are here to swap the panel over.
None of that is automatically untrue. Companies do get acquired and door-to-door is a legitimate sales channel. What makes it worth slowing down for is that the pitch is built around signing today, and everything you would want to check takes longer than the visit is designed to last.
- Ask for the licence number and the company's legal name, and write both down.
- Look them up on the state register before signing anything, not after.
- If they say your existing company sold its accounts, ring your existing company and ask.
- Never let anyone modify or remove an existing system on the strength of a doorstep conversation.
- A genuine offer survives you checking it overnight. That is the whole test.
What about the people, not the company
The contracting licence sits with the business and its qualifying licence holder. The technician who arrives at your door is working under that licence rather than holding one of their own, which is normal and not a problem in itself.
What is worth asking is whether that technician is an employee of the company you hired or a subcontractor. Both happen. It matters for who you chase when a sensor stops reporting six months later, and it is a question that gets a straight answer if you ask it plainly.
One more thing the register is good for after the fact. If a job goes badly, the licence is the route to a complaint that somebody is obliged to read — the state licenses the business, so the state has a process when the business does not put things right. Keep the licence number with your paperwork rather than only checking it once and forgetting it, because the moment you need it is the moment the company has stopped returning calls.
Questions people ask
- Is an alarm installer required to be licensed in Florida?
- Yes. Florida law makes alarm system contracting a licensed trade, and the definition covers laying out, installing, maintaining, repairing, monitoring, inspecting and servicing alarm systems for compensation. It is not limited to the installation itself.
- What is the difference between Alarm System Contractor I and II in Florida?
- Class I covers all types of alarm systems for all purposes, fire included. Class II covers all types other than fire. If your job involves a fire alarm system, that is the difference that matters.
- How do I check whether a security company is licensed in Florida?
- Search the Department of Business and Professional Regulation's free public licensee register at myfloridalicense.com. You can search by company name, by licence number, or by city and county, and confirm the licence is active before anyone visits.
- Does a licence mean the company is any good?
- No. It means they met the state's requirements and can be held to account by a regulator. Quality, responsiveness and honest contract terms are separate questions, and the licence says nothing about any of them.
